The GROOVYPETS Dog Remote Dog Training Collar Systems is a rechargeable dog collar system that allows you to train your dog remotely with a range of up to 1200 feet or 400 yards. The strong humane vibration command stops barking or other undesirable behaviors, while the shock buttons provide a level of pain for each dog. The adjustable dog collar strap fits most dogs 6-25 inches or 15-65 centimeters, and the remote has large color-coded buttons for easy access. The remote also features a two-tone rubberized coating that looks and feels great.
